The very definition of "each possibility" would be called brute force.

If you want to write a script to try each possibility, I'd use Perl with the cURL library. Basically use perl to keep track of what's being submitted, and curl to actually submit it. Shouldn't take more than a few seconds if you do it right.

This could be done using php and javascript... either using PHP CURL or an fsockopen, fputs, fgets method. I've never attempted to do it this way.. but.. I now have my next personal challenge for myself... to write my own PHP based brute force script.

It would be easy for php programmer, so I have wordlis.txt file on my server there are all possible passwords each in new line, so how to make php script thats takes text from 1. line sets form value to qqq submits, checks for errors, if no then stop, if error, clears form takes text from 2. line and repeats it till got no error. The password page is simple html form with submit button, when enter invalid pass its just says wrong next to it and i can try again.
